VENTILATING DEVICE.

To all whom it may concern Be it known that I, J AY LESLIE, a citizen ofthe United States, residing at Spring Valley, in the county of Fillmoreand State of Minnesota, have invented new and useful Improvements inVentilating Devices, of which the following is a specification.

An object of the invention is to provide a means for attachment betweena window and the casing thereof and arranged to provide efficientventilation for a room.

Among other features my invention embodies a plurality of casings, oneslidable within the other and ventilating pipes to extend outwardly fromthe said casings, the said casings being adapted for disposal betweenthe window and the casing thereof, so that one of the said pipes willextend into the room and the other said pipe will extend into theoutside atmosphere so that a current of air will pass into the outsidepipe, through the said casings and into the inside pipe or vice versa.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which Figure 1 is aperspective view of my device. Fig. 2 is a perspective view showing mydevice applied to a window with the window casing being broken away atone end to disclose the arrangement of my device relatively to thewindow. Fig. 3 is a vertical sectional View of my-ventilating device.

Referring more particularly to the views I provide a plurality ofcasings 10, 11, the

casing 10 being slidable within the casing 11. Connected to the casing10 and extending'downwardly therefrom is a pipe 12 and connected to thecasing 11 and extending upwardly therefrom is a pipe 13, the pipe 12being adapted to constitute an intake pipe and" the pipe 13 beingadapted to constitute an outlet pipe relatively to the connected casings10 and 11.

The pipes 12 and 13 are revolubly mount- Specification of LettersPatent.

ed on the casings 10 and 11 respectively and the casings 10 and 11 beingrelatively slidable can be disposed between a window 14 and a casing 15so that the casings 10 and 11 will extend along the entire edge of thewindow 14 and the lower edge of the casing 15 as shown in Fig. 2. Whenmy device is applied to a window at the upper end thereof so that thepipe 12 will be disposed exteriorly of the room and the pipe 13 willextend into the room, fresh air will pass into the pipe 12, thence intothe casings 10 and 11 and out of the pipe 13 into the room. By disposinga device similar to the one described at the lower end of the room. anybad air that is contained in the room can be exhausted therefrom and thesame will be exhausted outwardly through my device similar to the mannerin which fresh air is received into the room, except that the directionof the bad air through the casings will be opposite to the direction ofthe fresh air to be received in the room.

Having thus fully described the invention, what I claim as new, is

1. A ventilating device comprising a plurality of relativelytelescopical tubular casings, a pipe revolubly mounted on one of thesaid casings and a second pipe revolubly mounted on the other casing. l

2. A ventilating device comprising a plurality of relativelytelescopical tubular cas ings, a pipe revolubly mounted on one side ofone of the casings and a second pipe mounted on the opposite side of theother casing.

3. A ventilating device comprising a plurality of relativelytelescopical casings for insertion between a window and the casingPatented July 2, 1912.

thereof and pipes revolubly mounted on the ends of the said casings andextending laterally thereto.

In testimony whereof I affix my signature in presence of two witnesses.
